CVE-2018-16435
Little CMS (aka Little Color Management System) 2.9 has an integer overflow in the AllocateDataSet function in cmscgats.c, leading to a heap-based buffer overflow in the SetData function via a crafted file in the second argument to cmsIT8LoadFromFile.
Does this matter?
Lower severity and a low EPSS score (1.74%). Track it; it rarely justifies an emergency change on its own.
